Underwater Manta Ray Kites to Generate 20kW of Clean Energy in Alaska Waters
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Manta ray-inspired underwater kites are being developed to harness tidal currents in Alaska, producing 20 kilowatts of clean energy per unit with minimal environmental impact.
📈 One key stat: Each Manta kite can produce around 20 kilowatts of energy, making them viable solutions for small-scale applications in remote regions.
💬 One key quote: “Drawing inspiration from manta rays floating effortlessly underwater, this Manta kite system can be used in places like Alaska too that have already been seen as an energy source.”
1️⃣ The big picture: SRI International and UC Berkeley are developing underwater kites that mimic manta rays to generate clean energy from tidal currents. The project received $4.2 million from the Department of Energy’s Advanced Research Projects Agency-Energy through the SHARK’s program. These kite-like systems harness the power of ocean currents, tides, canals, and rivers through a reel-in pumping motion. Each Manta kite can produce approximately 20 kilowatts of energy while maintaining minimal environmental disruption.
2️⃣ Why is this good news: The Manta kite system offers an alternative clean energy source for communities unable to utilize solar or wind power infrastructure. Its polymer composite-coated foam structure ensures minimal harm to marine wildlife while generating continuous power. The system requires low installation and maintenance costs, making it accessible for remote and rural communities. These underwater generators can function in various water environments without disrupting natural marine habitats, providing a scalable solution to reduce dependence on fossil fuels.
3️⃣ What’s next: SRI International continues refining the Manta technology to overcome existing challenges. The team is engaging with stakeholders to minimize potential disruptions to fishing and boating activities. Researchers are exploring how the system can be optimally deployed in various marine environments including Alaska’s waters.
